1.2 Check electromagnetic switch Refer to Fig 58
(1)Disassemble the starter motor from the base-frame of starter motor, and prepare a 6V
battery.
(2)Connect the electromagnetic switch case and C wiring terminal to battery cathode with two
conducting wires.
(3)Connect the battery anode and receptacle S with another conducting wire, now the gear
shaft breaks cover suddenly. If coming away the C wiring terminal, the gear shaft should be on
the position protruding, this means the electromagnetic switch is in working order.
(4)While testing, please pay special attention that the turn-on time should be only 3 to 5
seconds, if not, the windings will be burnt out.

1.3 Motor disassembly Refer to Fig 59
(1)Disassemble the leading-out wire terminal from the electromagnetic switch wiring terminal.
(2)Loose the transfixion screw and the setscrew of carbon brush holder
(3)Take off the rear shield, stator, carbon brush holder, and armature in turn.
(4)Assembly sequence and disassembly sequence are opposite, smear some lubricant grease
on the end B of armature spline while assembling.
